Hi. Wondering if there are any PSU experts out there who could help. I’m trying to repair a PSU from a Compaq Portable II. I found I had a short on the 5V. Looking over the PSU I found a blown tantalum and replaced it. The 5V short was still there. Tracing back I found that if I removed a bobbin inductor the short on the 5V would go away. But when I tried the PSU I found that it seemed to be cycling – clicking noise and voltage cycling – as well as a resistor started to burn.

Does this make sense that the inductor would cause a short on the 5V or is this a red herring?
Is It an indication the inductor is bad?
Can anyone identify a replacement for it?

Thanks.
